Used in the output stage of audio amplifying equipment,
especially units designed to have ample reserve of
power-delivering ability. These tubes provide high
power output, sensitivity, and high efficiency. Power
output at all levels has low third- and higher-order
harmonics. Tubes require octal socket and may be
mounted in any position. It is especially important that
these tubes, like other power-handling tubes, be
adequately ventilated. For typical operation as push-pull
class A1, class AB1 (within maximum ratings), and class
AB2 amplifier, refer to type 6L6GC
